Oil Prices, Terms of Trade Shocks, and Macroeconomic Fluctuations in Saudi Arabia

The article investigates the sources of macroeconomic fluctuations in Saudi Arabia using structural vector autoregression methods and pays particular attention to oil prices and changes in terms of trade. Using a macroeconomic model tailored to the Saudi Arabian economy, the authors identify terms of trade, supply, balance of payments, aggregate demand, and monetary shocks. The results show that the Saudi Arabian price level, real exchange rate, and to a lesser extent output is vulnerable to terms of trade shocks. Moreover, Saudi Arabian terms of trade are driven by output, trade balance, and aggregate demand shocks. To stabilize output and the real exchange rate, Saudi Arabia ought to continue diversifying its production base and aim for a stable nominal oil price. (JEL E32 , Q43 , C22 )     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

Oil shocks and monetary policy rules in emerging economies

We examine the effects of shocks in the oil market on key macroeconomic variables in small open economies using a dynamic stochastic general equilibrium model with sticky prices and imperfect competition under different monetary policy rules. The numerical solutions show that the types of exchange rate regimes and monetary policies could partly explain the trends in macroeconomic volatilities considering negative shocks to oil supply (Hamilton, 1983) and positive shocks to oil demand (Kilian, 2009). These findings are confirmed in vector autoregressive responses for Chile and Israel with inflation targeting under flexible exchange regimes and Hong Kong with fixed regime.     

Monetary transmission in Spain: a structural cointegrated VAR approach

This paper analyses the monetary policy channels in Spain using a cointegrated structural VAR approach which explicitly accounts for endogenous policy reactions in a small open economy. Evidence is found of one cointegrating relation which is identified as a long-run money demand function. In addition, stability tests are applied to this relationship to assess whether there has been a change of monetary regime. The impulse-responses for the non-monetary shocks as well as the absence of the puzzles traditionally found in the empirical literature, suggest that the model specification identifies the monetary policy shocks correctly. Thus, according to our results, a monetary contraction causes a weak downward response in the price level, as well as an increase in both short and long-run nominal interest rates, a decrease in aggregate output and an exchange rate appreciation.     

Asymmetric effects of oil price shocks on stock returns: evidence from a two-stage Markov regime-switching approach

The asymmetric effects of oil price shocks on stock returns have attracted the attention of many researchers in the past several decades. Most of these researchers’ studies, however, do not separate out the sources of oil price shocks when examining the asymmetric effects. In this article, we address this limitation using a two-stage Markov regime-switching approach. Our results indicate that oil supply and demand shocks have a null or minimal impact on stock returns in a low-volatility regime and a statistically significant impact in a high-volatility regime. We observe that oil demand shocks affect stock returns significantly more than oil supply shocks. A positive aggregate demand shock significantly increases stock returns, whereas a positive oil-specific demand shock markedly decreases stock returns. These results have important implications for policymakers and investors.     

Oil dependency and exchange rate regimes in Arab oil economies: time to rethink the paradigm

This study examines implications of the current exchange rate regimes on the macroeconomic and growth performance of five Arab oil-producing countries: Saudi Arabia, the UAE, Sudan, Algeria and Yemen. The study evaluates alternative exchange rate regime policy options towards exploring an optimal exit strategy to ensure successful transition to more sustainable exchange rate regime, especially in the fixed regime economies of Saudi Arabia and the UAE. This study proposes the adoption of a transparent broad basket, band and crawl (BBC) regime by the Arab oil economies in order to provide a better alternative to the existing fixed pegs or dirty floats. However, it is imperative to note that, the timing of the exit from the current regime and the extent of institutional development and market sophistications are very critical to successful transition to more sustainable regime that would provide a larger scope for counter-cyclical policies and diversification in these economies.     

Foreign Money Shocks and the Welfare Performance of Alternative Monetary Policy Regimes*

The welfare properties of monetary policy regimes for a country subject to foreign money shocks are examined in a two‐country sticky‐price model. Money targeting is found to be welfare superior to a fixed exchange rate when the expenditure switching effect of exchange rate changes is relatively weak, but a fixed rate is superior when the expenditure switching effect is strong. However, price targeting is superior to both these regimes for all values of the expenditure switching effect. A welfare‐maximising monetary rule yields lower output and exchange rate volatility than price targeting for a wide range of parameter values.     

Oil prices and economic downturns: the case of Spain

We address the macroeconomic effects of an oil price shock in Spain. We apply a vector autoregression model (VAR) analysis to quarterly data for the Spanish economy since 1986, to elucidate the effects of variations in the oil price on the economy, considering the three main causes of disruptions in the oil markets: oil supply shocks, oil demand shocks and oil-specific (precautionary) demand shocks. We conclude that the effects in Spain strongly depend on the type of shock: the consumer price index (CPI) has mainly been influenced by oil demand shocks; output has only reacted to oil supply shocks; and monetary policy has mainly reacted after precautionary shocks. Second-round effects caused by the behaviour of nominal wages have not been found. Additionally, we discuss two facts: the ability of firms to increase markups in a context of rising demand and the procyclical role of monetary policy when faced with oil demand shocks.     

Structural VAR models for Malaysian monetary policy analysis during the pre- and post-1997 Asian crisis periods

This article conducts an in-depth investigation into building a Structural Vector Autoregression (SVAR) model and analysing the Malaysian monetary policy. Considerable attention is paid to: (i) the selection of foreign, policy and target variables; (ii) establish identifying restrictions and improve the estimates of impulse response functions; (iii) assess the importance of intermediate channels in transmitting monetary policy mechanism; and (iv) the way in which the 1997 Asian financial crisis affected the working of monetary policy. Malaysia is an interesting small open economy to study because, following this crisis, the government imposed capital and exchange rate control measures. The overall results suggest that the crisis and the subsequent major shift in the exchange rate regime have significantly affected the Malaysian ‘Black Box’. In the pre-crisis period, domestic variables appear to be more vulnerable to foreign monetary shocks. Further, the exchange rate played a significant role in transmitting the interest rate shocks, whereas credit and asset prices helped to propagate the money shock. In the post-crisis period however, asset prices play a more domineering role in intensifying the effects of both interest rate and money shocks on output, and the economy was insulated from foreign shocks.     

Re‐vitalizing money demand in the Euro area. Still valid at the zero‐lower bound

The analysis of monetary developments has always been a cornerstone of the ECB's monetary analysis and, thus, of its overall monetary policy strategy. In this respect, money demand models provide a framework for explaining monetary developments and assessing price stability over the medium term. It is a well‐documented fact in the literature that, when interest rates are at the zero‐lower bound, the analysis of money stocks become even more important for monetary policy. Therefore, this paper re‐investigates the stability properties of M3 demand in the euro area in the light of the recent economic crisis. A cointegration analysis is performed over the sample period 1983 Q1 and 2015 Q1 and leads to a well‐identified model comprising real money balances, income, the long‐term interest rate and the own rate of M3 holdings. The specification appears to be robust against the Lucas critique of a policy dependent parameter regime, in the sense that no signs of breaks can be found when interest rates reach the zero‐lower bound. Furthermore, deviations of M3 from its equilibrium level do not point to substantial inflation pressure at the end of the sample. Excess liquidity models turn out to outperform the autoregressive benchmark, as they deliver more accurate CPI inflation forecasts, especially at the longer horizons. The inclusion of unconventional monetary policy measures does not contradict these findings.     

Monetary policy and noise traders: A welfare analysis

This paper studies the choice of monetary policy regime in a small open economy with noise traders in forex markets. We focus on two simple rules: fixed exchange rates and inflation targeting. We contrast the above two rules against optimal policy with commitment under productivity shocks. In general, the presence of noise traders increases the desirability of a fixed exchange rate regime. We also evaluate the welfare impact of Tobin taxes in this milieu. These taxes help unambiguously in the absence of productivity shocks; their welfare impact under productivity shocks depends on the monetary regime in place and trade elasticity between domestic and foreign goods.     

Stability of Money Demand and Monetary Policy in Papua New Guinea (PNG): An Error Correction Model Analysis

An error correction model (ECM) is used to study the Properties of money demand and to evaluate the appropriate monetary policy in PNG. The study confirms that the determinats of money demand are real GDP, nominal interest and inflation rate. The income elasticity of money demand is very low. The demand for money in PNG was stable during 1979-95, suggesting that the monetary targeting regime by the PNG Central Bank is feasible. However, as PNG proceeds with economic reforms that Includes financial sector reform and a floating exchange rate regime, the stability of the demand for money may have to be re-examined periodically. The best approach for conducting the monetary policy in PNG is to target the inflation rate. [E41, E52, C22]     

A stable demand for money despite financial crisis: the case of Venezuela

The demand for broad money in Venezuela is investigated over a period of financial crisis and substantial exchange rate fluctuations. The analysis shows that there exist a long-run relationship between real money, real income, inflation, the exchange rate and an interest rate differential, that remains stable over major policy changes and large shocks. The long-run properties emphasize that both inflation and exchange rate depreciations have negative effects on real money demand, whereas a higher interest rate differential has positive effects. The long-run relationship is finally embedded in a dynamic equilibrium correction model with constant parameters. These results have implications for a policy-maker. In particular, they emphasize that with a high degree of currency substitution in Venezuela, monetary aggregates will be very sensitive to changes in the economic environment.     

Causes of Inflation in Europe, the United States and Japan: Some Lessons for Maintaining Price Stability in the EMU from a Structural VAR Approach

Price stability being among the primary goals of EMU monetary policy,it should be interesting to analyse thefactors that led to the disinflationarydevelopments of the last years. Using a structural VAR approach withlong-run identifying restrictions derived from an open-economy macromodel, various factors of inflation for Austria, Germany, Italy, the UnitedKingdom, the United States and Japan and the extent to which they havecontributed to inflation are analysed. These factors are energy price shocks, supply shocks, wage setting influences, demand and exchange rate disturbances and money supply surprises. The latter three are also used to calculate core inflation. Within a smaller model for aggregate EMU data, supply and demand influences are analysed. While supply and demand factors have generally contributed to the inflation decline, monetary policy, enhanced competition, low energy prices and moderate wage setting are featuring most prominent in the recent disinflation process.     

Exchange rates of oil exporting countries and global oil price shocks: a nonlinear smooth-transition approach

This paper models logistic and exponential smooth transition adjustments of real exchange rates for six major oil-exporting countries in response to different shocks affecting oil prices. The logistic form captures asymmetric and the exponential form symmetric adjustments in regards to positive and negative oil price shocks. We chose oil-exporting countries that do not peg their exchange rates. For most countries, we detect no statistically significant non-linearities for the adjustment process of real exchange rate returns, be they asymmetric or symmetric, in response to oil supply shocks, idiosyncratic oil-market-specific shocks, and speculative oil-market shocks. Exceptions are oil supply shocks in the UK and possibly Brazil, where exchange rates respond nonlinearly, though the effects are symmetric for both countries. On the other hand, global aggregate demand shocks, which are shocks not originating directly in the oil market, have nonlinear asymmetric effects on real exchange rate returns for Canada, Mexico, Norway and Russia, and nonlinear symmetric effects for Brazil and the UK.     

Supply shocks and the interdependence of macroeconomic stability under flexible exchange rates

This paper analyzes the effects of a change in the monetary policy of a large economy on the macroeconomic stability of a small open economy with high dependence on imported intermediate goods. The analysis is carried out using the Taylor framework where the money supply rule is specified by the degree of monetary accommodation of price shocks. A supply shock to the large country is transmitted as both demand and supply shocks to the small country. A shift toward less monetary accommodation by the large country is shown to increase both price and output instability in the small country through the supply side linkage, while it may enhance price or output stability through the demand side linkage. Simulation results for Germany and Japan suggest that the supply side effect on price stability is important and that the effect on output stability depends crucially on the importance of trade in goods between the large country and the country in question.     

Monetary shocks and asymmetric effects in an emerging stock market: The case of China

In this paper, we study the effect of monetary shocks on the Chinese stock market over the period of 2005 to 2011 with the MSVAR–EGARCH model. The evidence suggests that Chinese monetary policies have significantly asymmetric effects on the stock market in different time periods and market cycles. The effects of shocks from interest rate and reserve rate vary across market cycles but effects from money supply and exchange rate do not. Empirical evidence from the non-linear model shows that monetary policy changes increase stock market volatility, even though these monetary policies are often aimed at stabilizing macro-economic activities. The evidence suggests that both the market conditions and the effects on stock markets should be taken into consideration in monetary policy design and implementation.     

Asymmetric Shocks and Monetary Policy in a Currency Union

We analyze the conduct of monetary policy in a currency union in the face of asymmetric shocks. In particular, we compare the stabilization properties of a currency union versus alternative exchange rate arrangements. The relative performance of a currency union is shown to depend on the extent of economic integration in patterns of consumption and production and on the relative weights placed on price stability versus employment stability in the monetary authority's objective function.

RE-EXAMINING THE EFFECTIVENESS OF STABILISATION POLICY

This paper develops an alternative international macroeconomic model for evaluating the effectiveness of fiscal and monetary policy in stabilising national income under fixed and floating exchange rates. It encompasses national output and income, saving, investment, money and capital flows and linkages between the exchange rate, price levels and real interest rates consistent with international parity conditions. It demonstrates that the nature of government spending is pivotal to the effectiveness of fiscal policy, revealing that, ceteris paribus , higher public consumption expenditure contracts national income and depreciates the exchange rate, whereas higher productive public investment spending has opposite effects. The framework also shows that the effectiveness of fiscal and monetary policy as macroeconomic policy instruments is not ultimately dependent on the exchange rate regime.
